● If circuit breaker or fuse is often activated, stop the system and contact your service contractor.
● Check that the ground wire is securely connected. If the unit is not correctly grounded, it will lead
to electric shock. Do not connect the ground wiring to gas piping, water piping, lightning
conductor or ground wiring for telephone.
● Before performing any brazing work, check to ensure that there is no flammable material around
when using refrigerant. Be sure to wear leather gloves to prevent cold injuries.
● Protect the wires, electrical parts, etc. from rats or other small animals.
If not protected, rats may gnaw at unprotected parts, which may lead to fire.
● Fix the cables securely. External forces on the terminals could lead to fire.
● Install the air conditioner on a solid base that can support the unit weight. An inadequate base or
incomplete installation may cause injury in the event the unit falls off the base. Incomplete
connections or clamping may cause terminal overheating or fire.

● The air conditioner may not work properly under the following circumstances.
The power transformer provides the same power or power as the air conditioner. The electrical
equipment is too close to the power supply of the air conditioner. With the sharp change of power
consumption and switching action, the power supply of the air conditioner will generate a large
induction surge voltage.
